In the roadside safety community, there has been debate over the influence of vehicle and barrier type on rollover rates in traffic barrier crashes. This study investigated rollover rates between sport utility vehicles (SUVs), pickup trucks, and cars in vehicle-traffic barrier crashes and has examined the effect of barrier type on rollover risk for concrete barrier and metal barrier impacts. Th...

Vibrator, as a crucial vehicle of oil and gas exploration, is challenged by the complex terrains. The probability of rollover accident is therefore high in bumpy terrain in which the drivers’ life is seriously threatened. Finite element numerical analysis was used to study the injury of the driver’s head, neck and chest in the rollover accidents of domestic KZ-28 type vibrator on different cond...

Earlier studies by the authors have examined factors that contribute to rollover crash severity. These factors include: (1) belt use, (2) the number of quarter-turns aggregated according to number of vehicle inversions, and (3) the damage severity from planar impacts with fixed and non-fixed objects that occur before or during the rollover. Further research indicated that rollovers with severe ...

This study investigated the effects of shoe heel height on the rollover characteristics of the biologic ankle-foot system. Ten nondisabled adult female volunteers walked using three pairs of shoes with varying heel heights and at three walking speeds with each pair of shoes. Kinematic and kinetic data needed to calculate the rollover shapes of the ankle-foot systems of the participants were col...

Two different rollover crash scenarios were simulated with the software Madymo. The vehicle kinematics in the numerical simulation were prescribed by the use of sensor signals of real crash tests. The Madymo 50% Hybrid III dummy model as well as the Madymo human model was applied to these simulations and the model kinematics were analysed and compared. Differences in the kinematics of human and...

This paper is an empirical investigation of the asset pricing implication of rollover risk, the risk that a firm might not be able to refinance its due liabilities. I focus on the long-term debt rollover risk and use the proportion of long-term debt falling due within the year to measure a firm’s exposure to rollover risk. I find that firm-specific rollover risk coupled with deteriorating marke...

This paper presents an analysis of the rollover shape and energy storage and return in a prosthetic foot made from a compliant cantilevered beam. The rollover shape of a prosthetic foot is defined as the path of the center of pressure along the bottom of the foot during stance phase of gait, from heel strike to toe off. This path is rotated into the reference frame of the ankle-knee segment of ...

Background A void in real-world rollover data compilation was fi lled in 2002 with the release of “Characteristics of Fatal Rollover Crashes” (DOT HS 809 438.) Using the Fatality Analysis Reporting System (FARS), DOT HS 809 438 examined an important segment of the rollover population. It was shown in the referenced report that, generally, those without restraint and subject to ejection are the ...

 Rollover IRAs account for 43.2 percent of all IRA and Keogh assets, with regular IRA assets following very closely behind at 42.7 percent, while Roth IRAs account for 11.1 percent and Keoghs 3.0 percent. Among total IRA assets, rollover IRAs account for 44.5 percent of assets, regular IRAs 44.1 percent, and Roth IRAs 11.4 percent. Therefore, rollover IRAs account for a larger share of assets ...
